2 Installation
2.1 Guidelines
For standard temperature models, the ambient temperature of the installation
location, such as an IT rack, should be no greater than 45°C if the PDU is loaded to
its full nameplate current rating. The ambient temperature of the installation location
should be not greater than 60°C if the PDU normal current load is a maximum 50%
of the nameplate and individual receptacle ratings. (Note: load up to full nameplate
rating are permitted during short term abnormal operating conditions).
Install the PDU such that the amount of airflow required for safe operation of
equipment is not compromised.
Mount the PDU so that a hazardous condition is not achieved due to uneven
mechanical loading.
Follow nameplate ratings when connecting equipment to the branch circuit. Take
into consideration the effect that overloading of the circuits might have on
overcurrent protection and supplied wiring.
The PDU relies on the building installation for protection from overcurrent. A
certified overcurrent protection device is required in the building installation. The
overcurrent protection device should be sized according to the PDU’s nameplate
ratings and local/national electrical code.
Reliable earthing of rack-mount equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the
branch circuit. The PDU must be connected to an earthed socket outlet.
PDU is intended for restricted-access locations. Only qualified service personnel
should install and access the PDU.
For pluggable equipment, install the PDU so the input plug or appliance coupler may
be disconnected for service.
The PDU is intended for indoor use only. Do not install the unit in wet or outdoor
environments, and do not install it next to water tanks or plumbing.
The PDU is intended for use with TN, TT, or IT power supply systems.
Installation
1. Using appropriate hardware, mount unit to rack. (See next section for examples.)
2. Plug PDU into an appropriately-rated and protected branch-circuit receptacle.
3. Plug in the devices to be powered by the PDU.
4. Turn on each device connected to the PDU. Sequential power-up is recommended
to avoid high inrush current.
